OOO!, i like the looks of the Hitch Gate. There are a few unintended consequences.
If your TC sticks out the back farther than the end of the truck bed you must use an extension as you would with a trailer. This reduces the amount of 'tongue weight' for the tire carrier the farther out you go with that lever back there.
If your TC is a centered rear door type, how will you close the swing away once you are inside the camper? A side door TC would be the ticket if you were going this route.
Even with the one bolt slop tightener, like bike racks use, in the receiver you are going to get wobble. The way to fix that would be with chain and turnbuckle outriggers like this rack only on steroids:
Since i must carry two spare tires, I have thought long and hard about the good the bad the ugly about a homemade, HD swing away tire rack. The Hitch Gate, even with the consequences has some merit.
Someone needs to try one of these and give a report back on its effectiveness on a TC.
